Why the lessons work this way

Each choice comes from research on how people with ADHD learn.

• You’re shown how, step by step — not asked to figure it out.

  Students with ADHD learned much less from “discover it yourself” tasks than from being told the method directly.

  Haifa et al. 2025, npj Sci. Learn.
• One idea per screen. Lessons are split into short parts with a break screen.

  ADHD often comes with a smaller working memory, so less on screen at once and natural stopping points help.

  Mukherjee et al. 2021Huang-Pollock & Karalunas 2010Pimenova et al. 2026
• Worked examples, then examples with a missing step for you to fill in.

  Fading support gradually works better than jumping straight to solo problems. Seeing a common mistake also helps.

  Miller-Cotto & Medrano 2026Wesenberg et al. 2022
• Instant feedback on every answer. A hint after one miss; the answer after two.

  Delayed or missing feedback hits ADHD learners harder. Getting stuck for a long time just drains motivation.

  Luman et al. 2005De Meyer et al. 2021
• Quick checks come back in a review deck after 1, 3 and 7 days.

  Practising recall, spaced out over days, beats re-reading — including for students with ADHD.

• “Game plan” cards: a short checklist to follow for each problem type.

  Students with ADHD who were taught an explicit plan for worksheets improved their math scores more than ones who weren’t.

  Iseman & Naglieri 2011
• A progress bar, a saved spot and a score at the end.

  Seeing your own progress (self-monitoring) helps you stay on task.

  Gaastra et al. 2016

Honest note: apps like this tend to help a little, not a lot (Wong et al. 2023, review). Short daily sessions beat one long cram.
